BTR Filters & Medium Format

[shopper@xxxxxxxx]

Hello to all, I am looking for information on mounting an 87c filter 
behing the shutter of my medium format camera.  The archives 
have lots of "filters" but no between the rails.  I have a Bronica EC 
and have been using Roland Elliotts cut down 70mm 220 HIE wiith 
good results.  I seem to recall several months ago someone 
introducing the subject but I never saw a reply, maybe there was 
none.  A year or so back I remember WJ being "associated" with a 
Bronica EC (?).  

I'm sitting here in a serious snow storm--in Alexandria, Virginia 
more than three flakes can stop the Federal government--and going 
over my negatives and contact prints. I really love my 87c filter on 
my 35mm cameras and also love 220 HIE.  I would really like to 
get the two together.  Suggestions, ideas, referals?

Jim Wood
